OSX 10.7 shipped with ICU 4.6 which has Unicode 6.0

Yes, we can demand a better version on Linux and get it packaged if needs be, 
but we can't on OS X.  Keeping Harmattan support without an upgrade is nice 
too.

formatting it doesn't seemed to have changed much.

As for features, most of them are transparent, if you have a more recent 
version you get better localisation but the API isn't different to get it.  
The main one here seems to be Number Systems and Digit Sets.

I'll see how we're affected as I go, I may put some conditional code in 
depending on ICU version.  It's adding new features later that may be held up 
by a version bump.
